Maybe something you should consider as well is
- to reduce the Artillery frequence. (currently it's Arty spam most times)
- to increase PF and (Rifle)Nade damage (funny to fly around after an indirectly hit, but not what should happen )
- Check Spawn times. Altough it's a Beginner Server, Allies have a handicap on most maps due to short respawn time which is on some maps only 2-3 seconds apart [vice versa on Axis attack maps]
